Hello
I have an application that has many different threads.
The sound card's PCM buffer is full during playback, and one thread is currently in snd_pcm_wait() waiting for enough space to appear in the buffer before doing the next snd_pcm_write().
A different thread wants to flush the buffer. There are two types of flush: -
1) Immeadiately empty the buffer.

snd_pcm_drop() ?

2) Stop accepting snd_pcm_write() commands until the current buffer has drained.

snd_pcm_drain() ?

Thankyou, I will use snd_pcm_drop(), but as a side note, what actually does "snd_pcm_reset()" do.
Just resetting delay to 0 does not make much sense to me.
